</span> * @class Ext.Date
* A set of useful static methods to deal with date
* Note that if Ext.Date is required and loaded, it will copy all methods / properties to
* this object for convenience
*
* The date parsing and formatting syntax contains a subset of
* <a href="http://www.php.net/date">PHP's date() function</a>, and the formats that are
* supported will provide results equivalent to their PHP versions.
*
* The following is a list of all currently supported formats:
* <pre class="">
Format Description Example returned values
------ ----------------------------------------------------------------------- -----------------------
d Day of the month, 2 digits with leading zeros 01 to 31
D A short textual representation of the day of the week Mon to Sun
j Day of the month without leading zeros 1 to 31
l A full textual representation of the day of the week Sunday to Saturday
N ISO-8601 numeric representation of the day of the week 1 (for Monday) through 7 (for Sunday)
S English ordinal suffix for the day of the month, 2 characters st, nd, rd or th. Works well with j
w Numeric representation of the day of the week 0 (for Sunday) to 6 (for Saturday)
z The day of the year (starting from 0) 0 to 364 (365 in leap years)
W ISO-8601 week number of year, weeks starting on Monday 01 to 53
F A full textual representation of a month, such as January or March January to December
m Numeric representation of a month, with leading zeros 01 to 12
M A short textual representation of a month Jan to Dec
n Numeric representation of a month, without leading zeros 1 to 12
t Number of days in the given month 28 to 31
L Whether it&#39;s a leap year 1 if it is a leap year, 0 otherwise.
o ISO-8601 year number (identical to (Y), but if the ISO week number (W) Examples: 1998 or 2004
belongs to the previous or next year, that year is used instead)
Y A full numeric representation of a year, 4 digits Examples: 1999 or 2003
y A two digit representation of a year Examples: 99 or 03
a Lowercase Ante meridiem and Post meridiem am or pm
A Uppercase Ante meridiem and Post meridiem AM or PM
g 12-hour format of an hour without leading zeros 1 to 12
G 24-hour format of an hour without leading zeros 0 to 23
h 12-hour format of an hour with leading zeros 01 to 12
H 24-hour format of an hour with leading zeros 00 to 23
i Minutes, with leading zeros 00 to 59
s Seconds, with leading zeros 00 to 59
u Decimal fraction of a second Examples:
(minimum 1 digit, arbitrary number of digits allowed) 001 (i.e. 0.001s) or
100 (i.e. 0.100s) or
999 (i.e. 0.999s) or
999876543210 (i.e. 0.999876543210s)
O Difference to Greenwich time (GMT) in hours and minutes Example: +1030
P Difference to Greenwich time (GMT) with colon between hours and minutes Example: -08:00
T Timezone abbreviation of the machine running the code Examples: EST, MDT, PDT ...
Z Timezone offset in seconds (negative if west of UTC, positive if east) -43200 to 50400
c ISO 8601 date
Notes: Examples:
1) If unspecified, the month / day defaults to the current month / day, 1991 or
the time defaults to midnight, while the timezone defaults to the 1992-10 or
browser's timezone. If a time is specified, it must include both hours 1993-09-20 or
and minutes. The "T" delimiter, seconds, milliseconds and timezone 1994-08-19T16:20+01:00 or
are optional. 1995-07-18T17:21:28-02:00 or
2) The decimal fraction of a second, if specified, must contain at 1996-06-17T18:22:29.98765+03:00 or
least 1 digit (there is no limit to the maximum number 1997-05-16T19:23:30,12345-0400 or
of digits allowed), and may be delimited by either a '.' or a ',' 1998-04-15T20:24:31.2468Z or
Refer to the examples on the right for the various levels of 1999-03-14T20:24:32Z or
date-time granularity which are supported, or see 2000-02-13T21:25:33
http://www.w3.org/TR/NOTE-datetime for more info. 2001-01-12 22:26:34
U Seconds since the Unix Epoch (January 1 1970 00:00:00 GMT) 1193432466 or -2138434463
MS Microsoft AJAX serialized dates \/Date(1238606590509)\/ (i.e. UTC milliseconds since epoch) or
\/Date(1238606590509+0800)\/
</pre>
*
* Example usage (note that you must escape format specifiers with '\\' to render them as character literals):
* <pre><code>
// Sample date:
// 'Wed Jan 10 2007 15:05:01 GMT-0600 (Central Standard Time)'
var dt = new Date('1/10/2007 03:05:01 PM GMT-0600');
console.log(Ext.Date.format(dt, 'Y-m-d')); // 2007-01-10
console.log(Ext.Date.format(dt, 'F j, Y, g:i a')); // January 10, 2007, 3:05 pm
console.log(Ext.Date.format(dt, 'l, \\t\\he jS \\of F Y h:i:s A')); // Wednesday, the 10th of January 2007 03:05:01 PM
</code></pre>
*
* Here are some standard date/time patterns that you might find helpful. They
* are not part of the source of Ext.Date, but to use them you can simply copy this
* block of code into any script that is included after Ext.Date and they will also become
* globally available on the Date object. Feel free to add or remove patterns as needed in your code.
* <pre><code>
Ext.Date.patterns = {
ISO8601Long:"Y-m-d H:i:s",
ISO8601Short:"Y-m-d",
ShortDate: "n/j/Y",
LongDate: "l, F d, Y",
FullDateTime: "l, F d, Y g:i:s A",
MonthDay: "F d",
ShortTime: "g:i A",
LongTime: "g:i:s A",
SortableDateTime: "Y-m-d\\TH:i:s",
UniversalSortableDateTime: "Y-m-d H:i:sO",
YearMonth: "F, Y"
};
</code></pre>
*
* Example usage:
* <pre><code>
var dt = new Date();
console.log(Ext.Date.format(dt, Ext.Date.patterns.ShortDate));
</code></pre>
* <p>Developer-written, custom formats may be used by supplying both a formatting and a parsing function
* which perform to specialized requirements. The functions are stored in {@link #parseFunctions} and {@link #formatFunctions}.</p>

* which cannot be found in the passed string. If a corresponding default date value has not been specified in the {@link #defaults} hash,
